Fig. 1

In F0 female mammals, the F2 germline within the F1 embryo is exposed to environmental influences acting through the matriline during pregnancy. Thus, inter-generational effects occur in the F1 and F2 descendants and trans-generational effects occur in the F3 generation and further. If environmental exposure is passed through patriline of any taxonomic group or the matriline of taxonomic groups other than mammals, no embryonic germline exposure occurs so inter-generational effects only occur in the F1 and trans-generational effects occur in the F2 generation and further. Note that Figure is only used to provide a general overview and does not show all the taxonomic groups in which non-genetic inheritance can occur
